Acinic Cell Carcinoma of Parotid Gland Presenting as Disseminated Cutaneous and Subcutaneous Metastasis after 20 Years of Initial Presentation

Abstract

AbstractAcinic cell carcinoma (ACC) is an uncommon variety of salivary gland neoplasms, constituting about 17% of all salivary gland malignancies. Although ACC is a low-grade tumor, approximately 35% of patients experience recurrence and 16% have distant metastasis, often decades after the initial presentation. We report a rare case of disseminated metastatic ACC in skin and subcutaneous tissue in a 50-year-old male, with a history of surgery in parotid region 20 years back. After thorough search of literature, this is the second case being reported, to the best of our knowledge.
